Ground source heat pump technology principle: Ground source heat pump is a high-efficiency energy-saving and environment-friendly air-conditioning system that can use both underground shallow geothermal resources to supply heat and cool. The ground source heat pump can transfer energy from a low temperature heat source to a high temperature heat source by inputting a small amount of high-grade energy (electric energy). In the winter, the heat in the soil is “taken out”, and the temperature is raised and supplied to the room for heating; in the summer, the heat in the room is “taken out” and released into the soil, and the underground temperature can be balanced throughout the year.

Ground source heat pump advantages:

1. Ground source heat pump technology is a renewable energy utilization technology

Ground-source heat pump is a heating and air-conditioning system that uses shallow geothermal resources on the earth's surface (usually less than 400 meters deep) as a source of heat and heat for energy conversion. The shallow surface geothermal resource can be called ground energy (EarthEnergy) refers to the low-temperature heat energy absorbed by solar energy and geothermal energy in surface soil, groundwater or rivers and lakes. The shallow surface layer is a huge solar collector, collecting 47% of the amount of solar energy is more than 500 times that of human beings. It is not limited by geography, resources, etc. It is truly large and ubiquitous. This kind of storage is almost unlimited in the shallow surface of the earth. Energy makes the ground energy a form of clean renewable energy.

2. Ground source heat pump is a cost-effective energy-saving technology

The temperature of geothermal energy or shallow surface geothermal resources is relatively stable all year round, winter is higher than ambient air temperature, and summer is lower than ambient air temperature. It is a good heat source for heat pump and air conditioner. This temperature characteristic makes ground source heat pump ratio Traditional air conditioning systems operate at 40% higher efficiency, so energy savings and operating costs are reduced by about 40%. In addition, the relatively constant temperature of the ground energy makes the operation of the heat pump unit more reliable and stable, and also ensures the high efficiency and economy of the system.

According to the US Environmental Protection Agency's EPA estimate, designing and installing a good ground source heat pump can save 30-40% of the operating cost of heating and cooling air conditioners on average.

3. The environmental benefits of ground source heat pump are significant

The pollutant discharge of the ground source heat pump is equivalent to a reduction of more than 40% compared with the air source heat pump. Compared with electric heating, it is equivalent to a reduction of more than 70%. If other energy saving measures are combined, energy saving and emission reduction will be more obvious. Although the refrigerant is also used, it is reduced by 25% compared with the conventional air conditioner; it is a self-contained system, that is, the device can be completely sealed and sealed in the factory floor, and therefore, the probability of refrigerant leakage is greatly reduced. The plant operates without any pollution and can be built in residential areas without burning, no smoke, no waste, no need to stack fuel waste, and no need to transport heat over long distances.

4, ground source heat pump multi-purpose machine

Wide range of source heat pump systems can be used for heating and air conditioning. It can also be used for domestic hot water. It can be used in one machine to replace the original boiler and air conditioning two sets of devices or systems; it can be used in hotels, shopping malls, office buildings, Schools and other buildings are more suitable for heating and air conditioning in villas.

5, ground source heat pump air conditioning system maintenance costs are low

Under the same conditions, buildings using ground source heat pump systems can reduce maintenance costs. The ground source heat pump is very durable. It has very few mechanical moving parts. All the components are not buried in the ground and installed indoors, thus avoiding the harsh outdoor weather. The underground part can be guaranteed for 50 years and the above ground part can be guaranteed for 30 years. Therefore, the ground source heat pump is a maintenance-free air conditioner, which saves maintenance costs and allows the user's investment to be recovered in about 3 years.

In addition, the unit has a long service life of more than 15 years; the unit is compact and space-saving; the automatic control is high and unattended.

Ground source heat pump shortcomings

Of course, like anything, ground source heat pumps are not perfect, as their applications will be affected by energy policies and fuel prices in different regions, different users and countries; one-time investment and operating costs will vary from user to user. The use of groundwater is subject to local groundwater resources.
